Definitions

  • This invention relates to the art of transportation and storage of materials, and more particularly to a feeder of loose materials.
  • the invention can find a range of industrial applications associated with processing various fine grain, powder, pulverulent and fibrous loose materials in the material transmission lines operated in field conditions.
  • the latticed partition makes it impossible to use the feeder for discharging bristle-like fibrous and micro-fibrous loose materials, which tend to conjest on the latticed partition to draw the magnetic bodies away therefrom whereby discharge of the loose material is terminated.
  • a lattced partition exhibits resistance to the flow of loose material and affects the reliability of the feeder.
  • the object of the invention is attained by that in a feeder of loose materials comprising a hopper, a chamber arranged in the lower portion of the hopper and having a control means in the form of a latticed partition with kinematically disconnected magnetic bodies placed thereon, and a source of alternating magnetic field covering the chamber by magnetic lines of force it generates, according to the invention, the latticed partition has the form of a plurality of paralled vertically arranged plates secured in recesses of the chamber by means of horizontal pins to be capable of oscillating relative to these pins.
  • Such a construction of the feeder ensures orientation of the fibers of a fibrous loose material along the vertically arranged plates to facilitate their passage through gaps between the plates, reduce resistance of the latticed partition to the flow of loose material, and promote flow stability.
  • the vertically arranged plates are fabricated from a ferromagnetic material. Under the action of an alternating magnetic field these plates are caused to oscillate and impart vibration to the particles of fibers of the loose material, increase their fluidity and orientate the fibers along the vertically arranged plates. In addition, oscillation of the plates promotes faster passage of the loose material through gaps formed therebetween.
  • l is the distance between two adjacent plates
  • ⁇ is the maximum allowable deviation angle of the plates during their oscillation relative to the horizontal pins
  • h is the height of the horizontal pins.
  • the limitation in the length of the recesses is necessary in order that even at a maximum vertical movement of the plates and their maximum possible deviations during oscillation relative to the horizontal pins the smallest magnetic body would fail to pass through the latticed partition or get jammed between the two adjacent plates.
  • the plates are provided with projections above the horizontal pins for these projections to cooperate with the magnetic bodies. Sporadic impacts of the magnetic bodies on the projecting portions of the separate plates cause them to irregularly deviate at a considerable angle and facilitate the discharge of the fibrous loose material.
  • the invention makes it possible to simplify the discharge of fibrous loose materials, and ensure their pre-treatment for obtaining a material better suited for further processing.
  • the proposed feeder can be easily installed in any material transmission lines, including pressure and vacuum lines. It can be linked with automatic adjustment and control systems. If the proposed feeder is suitably connected to a microprocessor and a micromeasuring instrument, the entire system for discharging loose materials can be completely automated.
  • the feeder is noise- and pollution-free, requires small amount of power for operation and safe for the attendants.
  • the feeder can reduce the consumption of loose materials thanks to a more precise material metering and more reliable operation; the other advantage being that pre-orientation of fibers of the fibrous loose material improves the quality of the end product.
  • FIG. 1 is a cut-away axonometric view of a feeder of loose materials according to the invention provided with a round chamber;
  • FIG. 2 is an axonometric view of a feeder according to the invention with a rectangular chamber
  • FIG. 3 is an axonometric view of a latticed partition of the feeder having a rectangular chamber
  • FIG. 4 shows an axonometric view of a latticed partition of the feeder according to the invention having a round chamber
  • FIG. 5 shows a cross-sectional view of the feeder of loose materials according to the invention when no alternating magnetic field is induced therein;
  • FIG. 6 is a cross-sectional view of the proposed feeder during operation
  • FIG. 7 illustrates part of the latticed partition of the feeder according to the invention
  • FIG. 8 is one possible embodiment of a plate
  • FIG. 9 is a modified form of the plate having a projection extending throught the length of the plate
  • FIG. 10 is one more embodiment of the plate having a projecting portion
  • FIG. 11 is an alternative form of the plate of the feeder according to the invention.
  • FIG. 12 is a general view of the proposed feeder shown in the absence of an alternating magnetic field with the plates capable of movement in the vertical plane;
  • FIG. 13 is a general view of the feeder with the vertically movable plates during operation
  • FIG. 14 is an axonometric partially cut-away view of the round chamber provided with a control means shown in the absence of an alternating magnetic field;
  • FIG. 15 shows an axonometric partially cut-away view of the round chamber provided with control means during operation of the feeder
  • FIG. 16 is an axonometric view of the rectangular chamber provided with a control means in the absence of an alternating magnetic field;
  • FIG. 17 is an axonometric view of the rectangular chamber provided with a control means during operation of the feeder according to the invention.
  • FIG. 18 illustrates positions assumed by a magnetic body and two adjacent plates in the feeder according to the invention.
  • a feeder of loose materials comprises a hopper 1 (FIG. 1) containing a loose material 2 and provided in the bottom portion thereof with a substantially round chamber 3 having a control means in the form of a latticed partition 4 with kinematically disconnected magnetic bodies 5, and a source 6 of alternating magnetic field fed from an alternating current mains 7.
  • the latticed partition 4 is fashioned as a plurality of parallel vertically extending plates 8 secured in recesses 9 of the walls of the chamber 3 by means of horizontal pins 10 to oscillate relative to these pins 10.
  • FIG. 2 of the drawings represents an alternative embodiment of the proposed feeder provided with rectangular chamber 3 in which all the plates 8 function in equal conditions.
  • FIG. 3 The mutual positioning of the plates 8 in the recesses 9 of the rectangular chamber 3 is illustrated in FIG. 3, whereas FIG. 4 shows mutual positioning of the plates 8 in the recesses 9 of the round chamber 3.
  • the plates 8 can have projecting portions 11 (FIG. 7) cooperating with the magnetic bodies 5.
  • the projecting portions 11 can extend throughout the length of the plate 8. Alternatively, these projecting portions 11 (FIG. 10) can extend through part of the length of the plates 8.
  • the plates 8 may be bent lengthwise.
  • the plates 8 can be arranged in the recesses 9 so as to be capable of movement in the vertical plane, these plates 8 being preferably fabricated from a ferromagnetic material to facilitate cooperation with the magnetic field.
  • the chamber 3 (FIG. 13) is arranged in the area of action of the magnetic lines of force induced by the source 6 of alternating magnetic field.
  • the magnetic lines of force of the alternating magnetic field are shown by dotted lines in FIGS. 7, 13, 15 and 18.
  • FIGS. 14 and 15 illustrate mutual positioning of the plates 8 and magnetic bodies 5 in the round chamber 3, whereas FIGS. 16 and 17 show the same in the rectangular chamber 3.
  • the length H of the recess 9 should be less than the value of H 1 determined from: ##EQU2## where D is the minimum diameter of the magnetic body 5,
  • l is the distance between two adjacent plates 8
  • ⁇ is the maximum allowable deviation angle of the plates 8 when they oscillate relative to the horizontal pins 10, and
  • h is the height of the horizontal pin 10.
  • the feeder of loose materials according to the invention operates in the following manner.
  • a loose material 2 to be discharged is loaded into the hopper 1 (FIG. 1) cut off from the alternating current mains 7.
  • a cluster of the magnetic bodies 5 covers the latticed partition 4 to prevent inadvertent escape of the loose material 2 from the feeder.
  • the alternating magnetic field source 6 FIG. 6
  • an alternating electromagnetic field is induced in the chamber 3 of the feeder, this field causing three-dimensional random movement of the magnetic bodies 5.
  • the cluster of such bodies is broken into separate bodies 5 which occupy a substantially greater space due to an increase in the distance between such bodies 5. This promotes penetration of the loose material 2 through the bed of moving magnetic bodies 5 to the latticed partition 4 and escape of the loose material 2 from the feeder.
  • the proposed feeder When used with the regular types of loose materials, the proposed feeder is highly reliable in operation due to that resistance to the flow of loose material 2 is greatly reduced by the latticed partition 4.
  • the latticed partition 4 When feeding fibrous loose materials 2 having particles of anisometric shape, some of such particles tend to get stuck on the latticed partition 4 and assume a position across the plates 8. Therefore, these particles may congest and close the discharge of the loose material from the hopper.
  • the latticed partition 4 is so constructed as to prevent the formation of a layer of fibrous loose material 2 thereon.
  • the parallel plates 8 capable of independent oscillations relative to their horizontal pins 10 under the action of the alternating magnetic field or due to the mechanical effect of the magnetic bodies 5 causes reorientation of the jammed fibrous particles to result in their discharge through free spaces between the adjacent plates 8.
  • the plates 8 (FIG. 6) respond to an alternating magnetic field induced by the source 6 of alternating magnetic field. Throughout the operation of the alternating magnetic field source 6 of the plates 8 oscillate relative to their horizontal pins 10. Sporadic impacts delivered by the magnetic bodies 5 on the projecting portions 11 (FIG. 7) of the plates 8 affect the synchronism and rhythm of oscillations to result in independent spontaneous movement of the plates 8, which favours reorientation of the fibrous particles of the loose material 2 (FIG. 6).
  • the present invention makes it possible to use the proposed feeder of loose materials with fibrous, microfibrous and bristle-like materials, as well as to ensure a more reliable operation of the feeder.
  • the invention also enables to reduce the amount of loose material used for and improve the quality of the end product.
  • the structural simplicity of the feeder ensures long service life and amenability to employment with automatically controlled systems.
